In SuiteCommerce/SCA:
1. PCV is processed server-side
PCV rules (Customer Segments → Commerce Categories → Item Visibility) are evaluated by:
• the Elasticsearch index, and
• the server-side SSP applications.
But…
2. SMT Preview is purely client-side
SMT’s “Advanced Preview”:
• Only hides/shows Site Management content (banners, landing pages, etc.)
• Does NOT re-run item or category visibility indexing
• Does NOT impersonate customer segments at the SSP layer
👉 Because of this, products, categories, and search results will never change in SMT preview, regardless of the customer group you choose.
